HFBTE Ultrasonic Liquid Flow Meter Instruction Manual

1. Прадукт скончыўсяview

The HFBTE Ultrasonic Liquid Flow Meter is a highly reliable and accurate device designed for non-invasive flow measurement of various liquids in pipes. Utilizing transit-time measuring principles, this flowmeter offers a convenient and quick installation process without the need to cut off the flow, ensuring non-destructive installation.

The system comprises a main unit and external clamp-on transducers. This package includes three types of transducers: TS-2, TM-1, and TL-1, accommodating a wide range of pipe diameters.

2. Настройка і ўстаноўка

Proper installation is crucial for accurate measurements. The clamp-on design allows for installation without interrupting the flow or cutting the pipe.

2.1 Уключаныя кампаненты

• Асноўны блок: The central processing unit with display and keypad.
• TS-2 Transducer: Малы клamp-on transducer (45x25x28mm) for pipe diameters DN25~100mm (0.98 to 3.94 inches).
• TM-1 Transducer: Medium clamp-on transducer (64x39x44mm) for pipe diameters DN50~700mm (1.97 to 27.56 inches).
• TL-1 Transducer: Вялікі клamp-on transducer (97x54x53mm) for pipe diameters DN300~6000mm (11.81 to 236.22 inches).
• Signal Cables, Pipe Clamps, and Power Supply.

2.2 Choosing the Right Transducer

Select the appropriate transducer pair based on the pipe's outer diameter:

• TS-2: For pipes from DN25 to DN100 (0.98 to 3.94 inches).
• ТМ-1: For pipes from DN50 to DN700 (1.97 to 27.56 inches).
• TL-1: For pipes from DN300 to DN6000 (11.81 to 236.22 inches).

2.3 Couplant Application

A couplant is essential for effective ultrasonic signal transmission between the transducers and the pipe. Molybdenum Disulfide is recommended. Apply a sufficient amount of couplant to the entire contact surface of the transducers and the pipe wall before clamping them on.

2.4 Mounting the Transducers

1. Clean the pipe surface thoroughly at the chosen mounting location to remove any rust, paint, or debris.
2. Apply couplant evenly to the transducer faces.
3. Position the transducers on the pipe according to the measurement method (Z-method, V-method, etc.) and the calculated distance, ensuring they are firmly clamped. Refer to the main unit's manual for specific spacing calculations.
4. Connect the transducer cables to the main unit's designated ports.

2.5 Падключэнне харчавання

Connect the main unit to a power source. The unit supports DC8~36V or AC85~264V. Ensure the power supply matches the unit's requirements.

3. Інструкцыя па эксплуатацыі

The flow meter operates on the transit-time principle, measuring the time difference of ultrasonic signals traveling with and against the fluid flow.

3.1 Асноўныя аперацыі

1. Power on the main unit. The LCD display will illuminate.
2. Use the keypad to navigate through the menu options. The "MENU" button typically accesses the main menu, and arrow keys (▲/▼) are used for navigation. "ENT" confirms selections.
3. Input pipe parameters (outer diameter, wall thickness, material) and liquid type into the system. Accurate input of these parameters is critical for precise measurements.
4. Verify signal strength and quality. The display usually provides indicators for signal reception. Adjust transducer placement if signals are weak.
5. The unit will display real-time flow rate, totalized flow, and other relevant parameters.
